Abstract

In recent years, flexible devices have gained rapid development with great potential in daily life. As the core component of wearable devices, flexible tactile sensors are prized for their excellent properties such as lightweight, stretchable and foldable. Consequently, numerous high-performance sensors have been developed, along with an array of innovative fabrication processes. It has been recognized that the improvement of the single performance index for flexible tactile sensors is not enough for practical sensing applications. Therefore, balancing and optimization of overall performance of the sensor are extensively anticipated. Furthermore, new functional characteristics are required for practical applications, such as freeze resistance, corrosion resistance, self-cleaning, and degradability. From a bionic perspective, the overall performance of a sensor can be optimized by constructing bionic microstructures which can deliver additional functional features. This review briefly summarizes the latest developments in bionic microstructures for different types of tactile sensors and critically analyzes the sensing performance of fabricated flexible tactile sensors. Based on this, the application prospects of bionic microstructure-based tactile sensors in human detection and human-machine interaction devices are introduced.

摘要

近年来，柔性器件发展迅速，在日常生活中具有巨大潜力。作为可穿戴设备的核心部件，柔性触觉传感器因其重量轻、可拉伸和可折叠等优异特性而备受青睐。因此，人们开发了众多高性能传感器以及一系列创新制造工艺。人们已经认识到，对于实际传感应用而言，仅提高柔性触觉传感器的单一性能指标是不够的。因此，广泛期待对传感器的整体性能进行平衡和优化。此外，实际应用还需要新的功能特性，如抗冻性、耐腐蚀性、自清洁性和可降解性。从仿生学角度来看，可以通过构建能够提供额外功能特征的仿生微结构来优化传感器的整体性能。本文综述简要总结了不同类型触觉传感器仿生微结构的最新进展，并批判性地分析了所制备的柔性触觉传感器的传感性能。在此基础上，介绍了基于仿生微结构的触觉传感器在人体检测和人机交互设备中的应用前景。
